So, What Actually Is Low Oil Pressure?
Oil levels can be checked using your car’s dipstick.
Look, oil’s basically the lifeblood of your engine. It keeps everything slick and sliding nicely, stopping all those metal bits from grinding each other to pieces. If your engine’s running with low oil pressure, it means the oil isn’t pumped around properly. Could be the pump, sticky sensors, old gaskets… whatever the cause, it means the crank bearings, camshafts and all those important bits aren’t getting looked after and can get wrecked pretty quick.
A lot of modern cars – like your Mazda Demio, Hyundai Santa Fe, or VW Passat – have a wee dash light that’ll pop up if the oil pressure drops low. If you see it, best to pull over straight away, whether you’re crawling along Victoria Street during rush hour or trying to get through Dinsdale roundabout. Honestly, the risk of buggering your engine isn’t worth it. Cheaper to get a tow to the workshop than to fork out for a whole new engine.
If you pop into the workshop, one of our techs can check your oil pressure with proper tools, not just guesswork.
Common Reasons We See for Low Oil Pressure
Low oil level – Seen plenty of these in everything from Honda Fits to Toyota Estimas. Happens if you haven’t checked your dipstick in ages, or the last service got forgotten. Simple fix if you spot it early: just top up to the correct mark.
Oil leaks – Hamilton roads can be rough on seals. All those speed bumps on Te Rapa Straight or potholes round Frankton can jolt things loose. Sometimes it’s a slow leak, sometimes you’ll see a puddle on your drive in Rototuna. Worn seals, gaskets, or sump plugs are classic causes. As seals wear, oil sneaks out, pressure drops. Don’t ignore drips. More info here: Oil leak fixes in Hamilton >
Wrong oil type – We had a Nissan Qashqai come in from Cambridge last week, engine rattling like a shopping trolley. Wrong oil grade in the last service. Check your manual or talk to a proper mechanic – not all engines like the same oil. Advice here: How to pick the right type of oil >
Dud oil pump – Not super common, but we’ve seen it in some higher-mileage Suzuki Swifts and even a BMW 3 Series that’d done the rounds out Morrinsville way. If the pump’s crook, oil just doesn’t get round the engine. Damage can happen fast.
What Are the Signs Your Oil Pressure’s Low?
Oil pressure light – Like I said before, if that red oil can pops up on your dash, don’t ignore it.
Oil leaks and stains – If you spot oil under your car after parking at Centre Place or up the drive in Nawton, something’s not right.
Rough running or weird noises – Engine starting to clatter or make ticking noises, especially when idling? Had a woman with a Renault Megane from Tamahere in last week – her car sounded like a box of spanners, all thanks to low oil pressure.
Loss of power or limp mode – Sometimes, the car’s clever enough to save itself. You’ll notice it won’t rev much, and you’re crawling along like a tractor up Wairere Drive. Check Engine light usually comes on, too.
Overheating – Oil also helps keep the motor cool. If you’re constantly seeing the temp gauge high, especially on those muggy March days, get it checked pronto.
